I have a wireless Joey at the far end of the house that gets a network connection quality rating (using their diagnostics) of ~ 20, but it regularly fluctuates down to ~10-12 leading to a horrible viewing experience. I've tried all of the obvious repositioning tricks but without much luck. I'm considering running a new coax cable directly from the bedroom back to the wiring box where the Dish switch is on the outside of our house - then replace the wireless Joey with a wired Joey. Is that doable?
